"We have achieved this growth without compromising on asset quality or undermining risk management. Our non performing loans are about 2 percent."
Wickremasinghe said the bank was lending to all sector of the economy and also to customers in the former war torn areas in the North and the East.
The bank has a loyal customer base in the area as it was one of the few banks to operate in even separatist controlled areas during the island's 30-year war.Wickremasinghe said the bank was looking to boost its capital.
"We hope the government will re-invest our dividends as equity," he said.
Chief financial officer Asoka Rupasinghe said though its capital was strong, to grow fast in the future it had to have strong equity buffer to be able to absorb shocks.
